personally dont like 8000k, light output is not as great as 6000k or less.

Well just did this conversion using depo headlights and h7 hid kit. With the kit HID kit i got it was plug and play, no errors on the on-board computer!
The process is exactly the same using a d2s HID kit, just make sure the kit is canbus

I will agree with you light output is better at lower numbers, however depending on what company you buy your HID's from 8000 could be another company's 6.
